hi Jeff ,
Thanks for your reply.
But I did not use form to execute the request.
I trigger the datastore data insertion by one browser request, and it
can be seen on the log (yes, there is only one and only one request).
I have changed my code to below to see what happen to the datastore.
============
#coding=utf-8
from google.appengine.ext import db
class Order(db.Model):
time = db.DateTimeProperty(auto_now_add=True)
stri = db.StringProperty()
obj1 = Order(stri='y')
obj1.put()
obj2 = Order(stri='n')
obj2.put()
==========
Running the query of "SELECT * FROM Order order by time desc" , the
result is :
(so you can see the server seems to request the site again after I
have done so)
But if I request it by cron job , there are only 2 entities inserted,
instead of 4.
id=60002 n 2010-05-20 04:33:24.450649
id=20004 y 2010-05-20 04:33:24.389974
id=66004 n 2010-05-20 04:33:23.886866
id=35006 y 2010-05-20 04:33:23.774130
